Research Interests

My laboratory has an NIH-funded program of International Collaborations in Infectious Disease Research, in collaboration with the International Centre for Diarrhoeal Disease Research in Dhaka, Bangladesh, to analyze human mucosal immune responses following natural V. cholerae infection, to analyze gene expression in V. cholerae directly in human samples, to use human immune responses following cholera to identify bacterial genes uniquely expressed during human infection, and to use this information to develop an improved cholera vaccine.
